This has been EXTREMELY useful to enhance my understanding. Hats down.

YOU DESERVE A MILLION SUBSCRIBERS.

This channel is an absolute life saver. The only reason I’m going to get a decent grade in my exams

Impressive, comprehensive and detailed video. These teaching and learning resources will greatly benefit both teachers and students alike.

I don't normally comment on any chemistry videos, but this one, by far has to be the best organic vid explanation I've ever seen!!

Thanks, this helped me to understand the difference between reflux and distillation!!

absolutely fantastic video. My school does not have the equipment to carry out this experiment but everything makes more sense now. Keep the videos coming!

Absolute king. My chem teacher taught me nothing !!!!

I appreciate all the videos you have posted , thank you so much you're a great teacher

fantastic video- this makes so much more sense now- thanks!!

So grateful you've uploaded these! Really great explanations, thank you!

I watch all of your videos, they're so helpful and clear. Please make more videos, you make chemistry make sense.

omg my teacher tried to explain this in class and we even carried out the experiment but it was shit. Thanks a lot for this video now I understand everything much better...

Thank you for helping my understand the difference between reflux and distallation

I have a huge test tomorrow on redox, energetics and organics and this helped me so much!

Hi, omg a huge thanks to you! You eased the whole concept of reflux and distillation processes for me.

these videos are so good . i. cant. even.

The best chemistry resource out there!

Brilliant teacher! Thank you very much!

best O chem vid on youtube gang

i love this explanation and visualisation soooooo much. thank you :)))))

Thnk you best till now very clear and calm i like that thnk you

Hi sir. Thank you for this video. If water is formed as well when we react the oxidising agent with he alcohol, why isn't it condensed out first? Thank you.

Thank you sir for your great educational videos...i have a question please : in both techniques why aldehydes are the only ones that are evaporating ? , why alcohols are not evaporating also under heat?...thank you again

Thank you very much, I really appreciate this helpful video as I am going to carry this practical out soon :D

amazing

Hello. I would like to oxidise ethanol to obtain ethanal. I am able to set up the condenser. Could you please tell me the concentrations of the alcohol, the oxidising agent, and the acid you used to acidify the oxidising agent in order to obtain the aldehyde?

I have to do this practical with my class. Which alcohol did you use for the oxidation? I'm guessing not ethanol as the ethanal boils at 20C. I was wondering what you used - propan-1-ol? Thanks

How would you be able to get pure carboxylic acid out of the reaction mixture with the dichromate ions? Would you be able to use a separating funnel, recrystallisation or something? Thanks so much for all of these videos, I'm sure they will be used by chemistry students for generations. :D

Great video!

Nice video, great explanation. Can I use same system (distillation) for oxidation of methanol to methanal?

Sorry for my stupid question in advance but I am very new to all this and would like to be as safe as possible before trying anything my question being would it be safer to use a electric heating mantle or hot plate to heat the solvent in place of the open flame ? No disrespect intended just making sure before hand thanks in advance

Nice video, thanks.

So, when you oxidise a primary alcohol with [O] under reflux, you produce an aldehyde, and oxidising this aldehyde in a distillation position produces a carboxylic acid? But if we oxidise a primary alcohol under just reflux we produce an aldehyde and if we oxidise a primary alcohol under distillation we still get an aldehyde, so for a primary alcohol we must reflux and distillate to form carboxylic acid, and in secondary alcohols we can either reflux or carry out distillation because we will always form a ketone? (Sorry, just making sure I understood correctly :) )

and is water only produced in the first oxidation of primary alcohols?

I was just wondering when you are heating by reflux, how do you know if the reaction has gone to completion or how do you know how much of the carboxylic acid is present?

thank you so so so much for this you are an absolute GOD SEND i finally understand this THANK YOU SO MUCH !!!!!

I'm curious. Dichromate oxidizes primary alcohol all the way to carboxylic acid, right? how then can we get aldehyde from the process?

Use water bath,...they are flammable and could cause fire on a naked flame

Is this a Pag for Ocr A??

During the distillation process, why it is more efficient for the water to go from the bottom to the top? isn't it is just the same?

Could this method be used to get formaldehyde from methanol?

The explanation of distillation and reflux is very well done but what about safety? Like no gloves, no lab coat, open fire while working with highly volatile substance with a low flash point, no boiling chips, no fume hood (I mean, the vapors can be irritating)... I know that no vapor should be able to escape out of the system but still one never knows as the procedures can never be 100% perfect. This is just not OK...

why do you have to heat gently when distilling if the vapor produced is immediately distilled and collected forming an formaldehyde?

is it called oxidation because the alcohols lose electrons or because they gain oxygen?

how can I tell when all the reactant has reacted in reflux rxn method? Thank you

How can I determine when the reaction has fully finished?

Why is it better that the cool water moves up the condenser in the distillation set up?

No flames in organic chem laboratories. Most organic solvents are volatile and flammable. Yikes.

gyatttt

Omg I always thought [o] was oxygen so was confused how distillation got oxygen to react

hello

I wonder you
